Aluthermo®,Your partner in energy savingAluthermo®, the thin-layer reflective insulation system, has been used for many years both for new buildingsand in renovation. This flexible complex, consisting of several layers of aluminium, contains dry air enclosed in its inner films. The result is efficient energy-saving.Its exceptional adaptability makes it very easy to install. Aluthermo® can therefore be used in almost every ima-ginable field of thermal insulation. Its durability has been perfected by proven leading-edge technology, so that season after season, Aluthermo®

is the new standard in comfort.

Description of Aluthermo®

Aluthermo® is an insulating system that works by reflection. It consists of two layers separated by a honeycombstructure of air bubbles sealed in a fireproofed (fire retardant) polyethylene film, which in turn is covered onboth sides by a 30-micron thick pure aluminium foil that has been polished and treated against oxidation.

The various elements of Aluthermo® are assembled by thermal welding over the entire surface. The obtainedcomplex is semi-rigid.

The air enclosed inside the bubble films is dry and stable. Any condensation is therefore prevented within thetemperature ranges recommended for each thickness of Aluthermo®.

A+D 99% pure aluminium foil, 30 microns thickB+C Fire-retardant polyethylene film containing bubbles of dry and stable air

Description of Aluthermo Quattro®

Aluthermo Quattro® is the first thin, multi-reflector, multi-layer insulation system with all its surfaces fully ther-mally welded together.

Aluthermo Quattro® consists of two 30-micron thick outer layers of polished and anti oxidation-treated pure alu-minium, separated by two honeycombed layers of air bubbles enclosed inside a fire-retardant polyethylene film,together with two extra layers of pure aluminium foil and a fire-retardant and water-repellent polyethylene foam.

Aluthermo Quattro® therefore provides an almost impenetrable barrier against infrared radiation in both summerand winter. For easier installation, Aluthermo Quattro®is thermally welded over its entire surface, like all otherAluthermo® insulation systems.

The obtained complex is semi-rigid and consists of the following successive layers:

1. A layer of pure aluminium foil, 30 microns thick, treated against oxidation2. A layer of dry air bubbles enclosed in fire-retardant polyethylene3. A layer of pure aluminium foil treated against oxidation4. A fire-retardant and water-repellent polyethylene foam 5. A layer of pure aluminium foil treated against oxidation6. A layer of dry air bubbles enclosed in fire-retardant polyethylene7. A layer of pure aluminium foil, 30 microns thick, treated against oxidation

4.1.1. WATERPROOFING AND AIRTIGHTNESS

To reduce convection losses to a minimum, it is absolutely essential for the insulation to form aclosed system that is sealed to the air outside the building. This criterion is easily satisfied with Aluthermo®.Aluthermo® is laid over the full surface of the construction. The edges of the successive stripsof Aluthermo® are overlapped over a width of 5 to 10 cm and sealed by means of Aluthermoaluminium adhesive tape, with a with of 75 to 100 mm depending on the application.Since the Aluthermo® insulation is thermally welded over its entire surface, it can be cut at anypoint.A normal cutter is sufficient for cutting the insulation.

ALUTHERMO® ADHESIVE

The 50 µm thickness of aluminium on this special adhesive tape also guarantees optimal reflec-tion at the cutting points.To guarantee perfect adhesion, the surfaces must be free of dust and moisture, and after apply-ing the adhesive, the bonded area must be wiped with a dry cloth.

4.1.2. PRESERVING THE AIR GAP

Um To bring out the full insulating potential of Aluthermo® in protecting against energy exchangeby radiation, we recommend that you preserve an air gap of at least 2 cm on both sides ofthe Aluthermo®. To maximise the soundproofing effect, Aluthermo must be stretched outtight to prevent any point of contact with adjacent surfaces.

4.1.3. CRUSHING

In response to the problem of crushing of the insulation material by roof battens, for exampleover the rafters, purlins etc., Aluthermo® prevents thermal bridging by ensuring compensationbetween the timber and the honeycombed air bubbles.

INSTALLATION METHODS

4.

4.1. GENERAL

6.

In the case of insulation from the outsi-de, Aluthermo® is unrolled horizontallyover the rafters, starting at the bottomof the roof, and is provisionally fastenedto the rafters by means of 20 mm longstaples.

When laying the next strips, ensure a“tile-effect” overlap of 10 cm. Coverthis overlap with 100 mm wide alumi-nium adhesive tape supplied by ourcompany.

The spacing between rafters must notexceed 60 cm, and the Aluthermo®

strips must be stretched out tight.

4.2. INSTALLATION AS ROOF INSULATION

7.

8.

Firstly, counter-battens measuring a minimum of 24 mm thick by 4 to 5 cm wide mustbe fastened on top of the rafters, vertically in relation to the eaves, using twisted nailswith a minimum length of 60 mm or screws.

Secondly, lay the battens for attaching the roofing (tiles, slates etc.) parallel to theeaves and fix them to the counter-battens.

If decking is required in order to attach the roofing material (zinc, certain types of slateetc.), the wooden boards must be fixed parallel to the eaves above the counter-bat-tens.

The battens must then be installed as follows:

●

●

●

This method of installation guarantees a minimum air gap of 2 cm between the roofing and theAluthermo® insulation, thereby assisting infrared reflection by Aluthermo® and ensuring ampleventilation. We also recommend the installation of roof vents.

Since Aluthermo® is waterproof and airtight, there is no need for a roof lining or vapour barrier.

Make sure that the frame is perfectly dry before installing Aluthermo®.

To prevent air from the outside passing underneath the Aluthermo® insulation at the base of theroof, the Aluthermo® insulation must be positioned correctly.

4.2.1.2. Installation at the base of the roof

Unroll the first sheet of Aluthermo® parallel tothe eaves. The bottom edge of the Aluthermo®

must overhang the wall plate by a sufficientlength to enable it to be fixed to the wall plate.Stretch out the Aluthermo® and fix it tempo-rarily to the rafters with staples.Then fold the bottom edge of the Aluthermo®

down on to the wall plate, after making an incision if necessary, and fix it to the wall platewith staples.

Seal the entire assembly with aluminium adhe-sive tape to ensure that it is airtight.Then finish the roof insulation down to the gutter using a conventional roof lining fastenedto the Aluthermo® insulation with the aid of thespecial aluminium adhesive tape.

4.2.2. ROOF INSULATION FROM EXTERIOR WITHLATH DECK AS PART OF EXPOSED BEAM INTERIOR DESIGN

Construct a batten frame on top of the lath decking to establish an air gap between theAluthermo® and the decking.

This frame is formed by criss-cross battening:Start at the bottom of the surface to be insulated. At this level, parallel to the eaves, fasten abase batten having the same height as will be used for the vertical counter battens. Then nailthe counter-battens, measuring a minimum of 30 mm high by 50 mm wide, through the decking into the rafters.

Unroll the Aluthermo® insulation horizontally,parallel to the eaves, over these vertical counter-battens. Staple the bottom edge of theAluthermo® to the vertical side of the base batten, with a spacing of 5 cm between staples.Seal this joint with aluminium adhesive tape.

Lay the other strips of Aluthermo® insulation asdescribed in the General Principles, overlappingeach strip by 10 cm in “tile effect”. Cover eachoverlap with the aluminium adhesive tape.

Now fasten a second level of vertical counter-battens to the existing frame base, followed final-ly by the horizontal battens for attaching the roofing.

4.2.3. ROOF INSULATION FROM INTERIOR

Fasten a framework of laths measuring 30 cm thick by 5 cm wide to the wall to be insulated.Unroll the Aluthermo® insulation horizontally over this framework, forming an overlap of at least5 cm between successive strips.

Seal the overlaps and joins with the special aluminium adhesive tape supplied by Aluthermo.

Provisionally fasten the Aluthermo® insulation by stapling it to this wooden framework.The vertical laths of the framework must be spaced at approximately 60 cm. The perimeter lathsmust be positioned flush with the horizontal and vertical limits of the surface to be insulated.This framework establishes a stable air gap between the Aluthermo® insulation and the insu-lated wall.

Then fasten the counter-laths to the framework for the final metal or timber cladding.

If the cladding is in slate, fasten the laths for the slate cladding to the counter-laths.

4.3.2. INTERIOR WALL INSULATION

Aluthermo® can be unrolled and installed horizontally or vertically,ensuring a minimum overlap of 5 cm between strips, on a fra-mework of laths measuring 30 mm thick by 50 mm wide pre-viously fixed to the wall to be insulated.

Seal the overlaps and joins with the special aluminium adhesivetape supplied by Aluthermo®.

Provisionally fasten the Aluthermo® insulation by stapling it tothis wooden framework.

The vertical laths of the framework must be spaced at approxima-tely 60 cm. The perimeter laths must be positioned flush withthe horizontal and vertical limits of the surface to be insulated.

This framework thereby establishes a stable air gap betweenthe Aluthermo® insulation and the insulated wall.

Then fasten the counter-laths to the framework for the interiorfinish (plasterboard, wood panelling etc.).

Use the same procedureas for interior walls.

Make sure that the structural floor isclean and smooth. If necessary, installa layer of plastic foam before layingthe Aluthermo®.

Spread out the Aluthermo® without fol-ding it up along the adjacent walls.

Do not overlap the different strips ofAluthermo® but lay them edge to edge,sealing the joins with the aluminiumadhesive tape supplied by Aluthermo®.

Then install a layer of particle boardbefore fitting the floating floor.

Unroll and staple the Aluthermo® insu-lation to the timber framework, sealingthe overlaps with the aluminium adhe-sive tape supplied by Aluthermo®.

Then screw laths measuring a minimum of 3 cm thick by 5 cm wide to the wooden floor beams.

Fasten the wood or particle board flooring to these laths.

If the wood floor is laid on concrete slab instead of on a timber framework, the insulation mustbe laid out and stapled to laths spaced at a maximum of 60 cm, previously fixed to the con-crete, sealing the overlaps between successive strips with the aluminium adhesive tape supp-lied by Aluthermo®.

Then screw laths measuring a minimum 3 cm thick by 5 cm wide to the base laths.

The wood or particle board floor can then be fixed to these top laths.
